Of all SAT subject tests, the Biology E/M test was the only SAT II that allowed the test taker a choice between the ecological or molecular tests. A set of 60 questions was taken by all test takers for Biology and a choice of 20 questions was allowed between either the E or M tests. This test was graded on a scale between 200 and 800.
Metapopulation models examine patch dynamics over time to answer potential questions about spatial and demographic ecology. The ecology of metapopulations is a dynamic process of extinction and colonization. Small patches of lower quality (i.e., sinks) are maintained or rescued by a seasonal influx of new immigrants.
In ecology, an ideal free distribution (IFD) is a theoretical way in which a population ' s individuals distribute themselves among several patches of resources within their environment, in order to minimize resource competition and maximize fitness.
Resource Selection Functions require two types of data: location information for the wildlife in question, and data on the resources available across the study area. Resources can include a broad range of environmental and geographical variables, including categorical variables such as land cover type, or continuous variables such as average ...
The test was comprehensive and covered—in equal proportions—molecular biology, organismal biology, and ecology and evolution. [7] This exam, like all the GRE subject tests, was paper-based, as opposed to the GRE general test which is usually computer-based. It contains 194 questions which were to be answered within 2 hours and 50 minutes.
Population ecology is a sub-field of ecology that deals with the dynamics of species populations and how these populations interact with the environment. [15] It is the study of how the population sizes of species living together in groups change over time and space, and was one of the first aspects of ecology to be studied and modelled mathematically.
Applied ecology – sub-field within ecology that considers the application of the science of ecology to real-world (usually management) questions – the practice of employing ecological principles and understanding to solve real world problems (includes agroecology and conservation biology);
Also called range fragmentation, disjunct distributions may be caused by changes in the environment, such as mountain building and continental drift or rising sea levels; it may also be due to an organism expanding its range into new areas, by such means as rafting, or other animals transporting an organism to a new location (plant seeds consumed by birds and animals can be moved to new ...
